Abstract

This work is based on the design and implementation of a led matrix display whose display at any point in time is controlled by a keypad. The display is built around ATMEL’s 89C52 microcontroller from 8051 families. The desired messages to be displayed at intervals of time is programmed and attached to different buttons on the display system, so that at any point in time, the message desired to be displayed is selected with the corresponding button.
